Question: What is the importance of ozone layer?

The ozone layer is a natural layer of gas in the upper atmosphere which protects humans and other living things from the harmful ultraviolet (UV) rays of the sun.

What is the important of ozone layer?

Why is Ozone Layer important? Ozone protects the Earth from harmful ultraviolet (UV) rays from the Sun. Without the Ozone layer in the atmosphere, life on Earth would be very difficult. With a weakening of the Ozone Layer shield, humans would be more susceptible to skin cancer, cataracts and impaired immune systems.

What is the importance of the ozone layer quizlet?

Why is the ozone layer important? This layer acts as a filter to prevent too much of the harmful ultraviolet light in sunlight from reaching earth.

What is ozone layer Class 9?

“The ozone layer is a region in the earths stratosphere that contains high concentrations of ozone and protects the earth from the harmful ultraviolet radiations of the sun.”

What is ozone layer short answer?

What is the ozone layer? The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earths surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.

What is ozone layer in Class 10?

What is the Ozone Layer? The ozone layer is the layer present in the Stratosphere. It absorbs the harmful ultraviolet rays that come from the sun. Moreover, it causes harmful radiation that has a high concentration of ozone (O3) which is harmful to living beings on the earth.

What are the harmful effects of ozone layer?

Ozone layer depletion causes increased UV radiation levels at the Earths surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.

How does the ozone layer protect us?

The stratospheric ozone layer is Earths “sunscreen” – protecting living things from too much ultraviolet radiation from the sun. The emission of ozone depleting substances has been damaging the ozone layer.

What are the harmful effects of ozone Class 9?

Ozone layer depletion causes increased UV radiation levels at the Earths surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.

How ozone layer is formed?

Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The ozone layer, approximately 6 through 30 miles above the Earths surface, reduces the amount of harmful UV radiation reaching the Earths surface.

What are the two uses of ozone?

Uses of ozone:Ozone is used for air purification at crowded places like cinema halls, tunnels, railways, etc.In sterilizing drinking water by oxidising all germs and bacteria.For bleaching ivory, oils, starch, wax and delicate fabrics such as silk.In the manufacture of synthetic camphor, potassium permanganate, etc.

What are the two uses of ozone layer?

1.It absorbs harmful UV rays from sun. 2. They reflects infrared radiation.

Why is it called ozone layer?

The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earths surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.

What is ozone layer and its effects?

The ozone layer is a natural layer of gas in the upper atmosphere that protects humans and other living things from harmful ultraviolet (UV) radiation from the sun. The ozone layer filters out most of the suns harmful UV radiation and is therefore crucial to life on Earth.

What are the health effects of ozone?

What health problems can ozone cause?Cause coughing and sore or scratchy throat.Make it more difficult to breathe deeply and vigorously and cause pain when taking a deep breath.Inflame and damage the airways.Make the lungs more susceptible to infection. •May 5, 2021

What will happen if we destroy the ozone layer?

radiation. A diminished ozone layer allows more UV radiation to reach the Earths surface. For people, overexposure to UV rays can lead to skin cancer, cataracts, and weakened immune systems. Increased UV can also lead to reduced crop yield and disruptions in the marine food chain.
